The Vagina’s Part in Sex and Reproduction

The vagina is the muscular tube that provides the passageway in the outside of the body to the uterus (uterus ). The vagina gets the capability to change in size to accommodate sexual sex and supply the”birth canal” through which a baby could be delivered.

Structure of this Vagina

The vagina is composed of tissues, fibers, nerves, and nerves. The outermost mucosal tissue is underpinned by a layer of connective tissue that work together to create mucus to get vaginal lubrication.

Beneath these is a layer of smooth muscle, which can contract and expand, followed by another layer of connective tissue called the adventitia.

The vagina is placed between the vulva (the external genitalia) and the cervix (the narrow, neck-like passage that separates the vagina from the uterus).

The overall arrangement of the vagina is as follows:

  • The opening of the vagina lies between the anus and the opening of the urethra (through which urine leaves the body). The vaginal and urethral openings are guarded from the labia.
  • Right beneath the urethra lies the introitus, also referred to as the vestibule or the opening to the vagina.
  • The vaginal canal then travels backward and upward, involving the cervix at the front along with the rectum at the trunk.
  • Since the far end of the vaginal passage, the ectocervix (the outside section of the cervix) bulges prominently into the vaginal canal.

The period of the vagina can vary in women of child-bearing age from between 2.5 inches to 3.5 inches on average.

Concerning lubrication, vaginal secretions can increase during sexual arousal, pregnancy, and distinct phases of menstruation. Throughout the menstrual period, the mucous tissue will thicken and also the composition of the mucus tends to change to better facilitate fertilization.

The Vagina and Sexual Intercourse

During sexual stimulation, the mucosal membranes of the vagina will begin to produce more lubrication since the vagina grows both in width and length.

This reduces the friction and risk of injury during vaginal penetration.

The vagina can continue to lengthen as a female become completely aroused since the cervix takes the opposite tack and starts to retract. This can cause the uterus to grow into the pelvis and make what’s called the”ballooning effect” where the vaginal walls stretch and contract around the penis to provide stimulation and promote climax.

The vagina itself does not have many nerve endings that’s the reason why a lot of women cannot achieve sexual stimulation from vaginal penetration alone. On the flip side, the clitoris is more full of nerves and may work in tandem with the vagina to achieve orgasm during sexual intercourse.

The Vagina at Childbirth

During childbirth, the vagina provides the passageway through which the baby is delivered. When labor starts, a woman with typically experience vaginal discharge, labor contractions, the rupture of membranes, and the gush or stream of amniotic fluid from the vagina.

As delivery approaches, the cervix will begin to soften and narrow, allowing the infant to fall in the pelvis. The infant will then start to eliminate the support of the cervix as contractions start and the cervical os (opening) begins to dilate.

When the cervical dilation is bigger than four inches (10 centimeters), the baby will pass from the uterus to the vagina. The structure of this vagina is such it is ready to stretch to many times its normal diameter to accommodate delivery.

Following pregnancy and the yield of the standard estrogen stream, the vagina will probably go back to its approximate pre-pregnancy condition in about six to eight weeks.
